Geogrid-Viewer tracklogs (.log) (ggv_log)

This format can...

read and write tracks

Binary track logs used by the Geogrid™-Viewer, a very
popular product in Germany.

GPSBabel has full support for version 1.0 of this file format.

We can also read some GPS data (including coordinates) from version 2.5. But
it seems, that this newer version no longer stores time stamps. This can be
a problem when converting to other formats or if you want to use our track filter.
